Title
Quality Enhancement of Audio Watermarking for Data Transmission in Aerial Space Based on Segmental SNR Adjustment
Abstract
Audio watermarking techniques can be used not only as a copyright protect system but also as a short-range wireless data transmission system between a loudspeaker and a microphone. To send data through aerial space using acoustic signal, the length of frequency analysis window should be longer than the reverberation time, which, however, can degrade the quality of watermarked audio signal. In this paper, we propose an audio quality enhancement technique for acoustic data transmission application based on segmental SNR adjustment. The acoustic data transmission system which employs the proposed audio watermarking technique with long frequency analysis window showed better transmission performance than the previous system.
